BOX-STRAP.

SPECIFICATION forming part of Letters Patent No. 773,271, dated October 25, 1904.

Application filed July 10, 1903. Serial No. 164,939. (No model.)

To all whom it may concern.-

Be it known that LOTTO ARENDT, a citizen of the United States,and aresident of Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Box-Straps, of which the following is a specification.

My invention relates to that class of boX- straps which is made of wire; and the object of my invention is to provide a strap of that class which will lie flat against the box without beingfiattened and which will afford a suitable countersink for the head of the fasteningnails without cutting the wire.

To this end my invention consists in a twin wire, the two strands of which are drawn so closely together as to be united at their inner edges, the strap thus formed being spread at suitable intervals by separating the two wires sufiiciently to admit the passage of afasteningnail.

One application of my invention is shown in the accompanying drawings, in which Figure 1 is a top view. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a section on line 3 3 of Fig. 1.

Same letters indicate similar parts in the diiferent figures.

A B are two round wires of any convenient size drawn through a die so close together as to be united at their inner edges, as shown in a, without leaving sufficient space for the entry of a nail point. At convenient intervals these wires are forced apart to make an opening 0 of suitable shape and size to allow the passage through it of the body of a fasteningnail, but not of the head, the head resting upon the natural countersink formed by the rounded edges 6 b of the two wires. It will be seen that this strap provides a reversible countersink, the rounded edges 0 0 being similar to the other rounded edges. The strap therefore may be used either side up.

Among the advantages of my improved boxstrap may be mentioned, first, that it combines the lightness, strength, and cheapness of a round drawn wire with the capacity of lying flat against the box or package to which it is applied, and thereby not so likely to cut the floor or anything with which it may come in contact, as would be the case if the wires were twisted over each other, so as to project more at some points than at others; second, a natural and reversible countersink is provided without weakening the strap by flattening or cutting away any portion of the material. The

thin head of the wire nail usually employed with these box-straps rests in this countersink with its outer edge'flush with the surface of the strap, so that it cannot injure anything W. P. PREBLE, J r., RAE BATTERSBY.
